Clostnature Crux Lightweight Backpacking Tent - Ultralight 1P/2P/3P/4P

In this review of the Clostnature Crux Lightweight Tent the bottom line is clear: it is aimed at backpackers who prioritize low weight and reliable weather protection. The tent's standout feature is its combination of an ultralight packed weight and a high-waterproof polyester fly with PU 5000 coating, which means the tent delivers solid dryness and shelter without adding bulk to a pack. For solo and small-group hikers who need quick setup, roomy internal space relative to weight, and durable components, this Clostnature tent is a practical, no-nonsense option.

Key Features

• Waterproof fly and bathtub floor: The polyester rain fly with PU 5000 coating and factory-sealed seams keeps the interior dry in heavy rain and reduces seepage risk.
• Ultralight trail weight: With a minimum trail weight of about 2.97 lbs (1.35 kg) for fly, inner tent and poles, it noticeably lowers load for long hikes.
• Compact pack size: Packs down to roughly 15in x 5.1in x 5.1in so it easily fits in most backpacks without dominating space.
• Fast freestanding setup: Two aluminum poles and a freestanding design allow one-person pitching even without prior experience.
• Well ventilated interior: Mesh inner walls improve airflow to reduce condensation while still keeping insects out during warm nights.
• Secure vestibule storage: A large side vestibule shelters pack and boots from weather and keeps the sleeping area uncluttered.

Who It's For

The Clostnature Crux is best for solo backpackers or small parties who want a lightweight shelter that still offers weatherproofing and decent internal space; its 7ft 3in by 2ft 8in footprint and 3ft peak height make it comfortable for a sleeping pad and some gear. Hikers doing multi-day treks, bikepackers or mountaineers who need a resilient, quick-pitch tent will find its combination of weight, durability and waterproofing attractive.

Those who should look elsewhere include car campers who want luxury features or families needing much larger living space, and ultralight purists who demand even lower grams-per-person than this tent provides. If you require a heavy-duty four-season mountaineering tent for extreme alpine storms, choose a purpose-built expedition shelter instead.

Pros & Cons

Pros

• Very light for its size, making it a good choice for backpacking and long approaches.
• High waterproof rating and sealed seams that keep the interior dry in rain.
• Easy, freestanding setup with two aluminum poles that a single hiker can manage quickly.

Cons

• Not a specialized four-season tent; extremely harsh alpine storms may exceed its intended use.
• Weight is light but not at the absolute ultralight extreme some thru-hikers pursue.
